AbstractPeriods of absence from supervised group exercise while maintaining physical activity might be a frequent pattern in adults' exercise habits. The aim of the present study was to determine detraining effects on musculoskeletal outcomes after a 3-month detraining period in early post-menopausal, osteopenic women. Due to the COVID-19 pandemic, we terminated the 18-month randomized controlled ACTLIFE exercise intervention immediately after the 13-month follow-up assessment. This put an abrupt stop to the high-intensity aerobic and resistance group exercise sessions undertaken three times per week by the exercise group (EG: n = 27) and the gentle exercise program performed once per week for the attention control group (CG: n = 27); but both groups were permitted to conduct individual outdoor activity for the 3-month lock-down period. Study endpoints were lean body mass (LBM), bone mineral density (BMD) at the lumbar spine (LS), maximum hip-/leg extension strength and power. Detraining-induced reductions of LBM, hip/leg strength and power (but not BMD-LS) were significantly greater (p < 0.001 to p = 0.044) compared with the CG. Significant exercise effects, i.e. differences between EG and CG, present after 13 months of exercise, were lost after 3 months of detraining for LBM (p = 0.157) and BMD-LS (p = 0.065), but not for strength (p < 0.001) and power (p < 0.001). Of note, self-reported individual outdoor activities and exercise increased by about 40% in both groups during the lock-down period. Three months' absence from a supervised group exercise protocol resulted in considerable detraining effects for musculoskeletal parameters. Thus, exercise programs for adults should be continuous rather than intermittent.Trial registration number: ClinicalTrials.gov: NCT04420806, 06.05.2020.

Background:Clinical practice guidelines recommend that exercise is an essential component in the self-management of Ankylosing Spondylitis (AS). Attending supervised interventions requiring periodic medical center visits can be burdensome and patients may decline participation, whereas, effective home-based exercise interventions that do not need regular medical center visits are likely to be more accessible and acceptable for patients with AS. Recently, increasing evidences have been accumulated that the wearable devices could facilitate patients with inflammatory arthritis by giving exercise instructions and improving self-efficacy. Therefore, patients with AS may benefit from an effective technology-assisted home-based exercise intervention.Objectives:To investigate the efficacy of a comprehensive technology-assisted home-based exercise intervention on disease activity in patients with AS.Methods:This study was a 16-week assessor-blinded, randomized, waiting-list controlled trial (ChiCTR1900024244). Patients with AS were randomly allocated to the home-based exercise intervention group and the waiting-list control group. A 16-week comprehensive exercise program consisting of a moderate intensity (64%-76% HRmax) aerobic training for 30min on 5 days/week and a functional training for 60min on 3 days/week was given to patients in the intervention group immediately after randomization, with 1.5h training sessions for two consecutive days by a study physical therapist at baseline and Week 8. The aerobic exercise intensity was controlled by a Mio FUSE Wristband with a smartphone application. The functional training consisted of the posture training, range of motion exercises, strength training, stability training and stretching exercises. Patients in control group received standard care during the 16-week follow-up and started to receive the exercise program at Week 16. The primary outcome was ASDAS at Week 16. The secondary outcomes were BASDAI, BASFI, BASMI, ASAS HI, peak oxygen uptake, body composition and muscle endurance tests. The mean difference between groups in change from baseline was analyzed with the analysis of covariance.Results:A total of 54 patients with AS were enrolled (26 in intervention group and 28 in control group) and 46 (85.2%) patients completed the 16-week follow-up. The mean difference of ASDAS between groups in change from baseline to 16-week follow-up was −0.2 (95% CI, −0.4 to 0.003, P = 0.032), and the mean change from baseline was -0.4 (95% CI, -0.5 to -0.2) in the intervention group vs -0.1 (95% CI, -0.3 to 0.01) in the control group, respectively. Significant between-group differences were found between groups for BASDAI (−0.5 [95% CI, −0.9 to −0.2], P = 0.004), BASMI (−0.7 [95% CI, −1.1 to −0.4], P <0.001), BASFI (−0.3 [95% CI, −0.6 to 0.01], P=0.035), peak oxygen uptake (2.7 [95% CI, 0.02 to 5.3] ml/kg/min, P=0.048) and extensor endurance test (17.8 [95% CI, 0.5 to 35.2]s, P=0.044) at Week 16. Between-group differences were detected in ASAS HI (−0.9 [95% CI, −1.7 to −0.1], P=0.030), body fat percentage (−1.0 [95% CI, −2.0 to −0.01] %, P=0.048) and visceral adipose tissue (−4.9 [95% CI, −8.5 to −1.4] cm2, P=0.008) at Week 8, but not at Week 16. No significant between-group differences were detected in the total lean mass, time up and go test and the flexor endurance test during the follow-up.Conclusion:Comprehensive technology-assisted home-based exercise has been shown to have beneficial effects on disease activity, physical function, spinal mobility, aerobic capacity, and body composition as well as in improving fatigue and morning stiffness of patients with AS.References:[1]van der Heijde D, Ramiro S, Landewé R, et al.

PURPOSE: To evaluate the effect of a purpose-designed exercise program on performance-related musculoskeletal disorders (PRMDs) and associated risk factors in a sample of professional orchestral musicians. METHODS: A 10-week exercise program was made available to full-time musicians employed by the eight premier symphony orchestras of Australia. Questionnaires were administered before, immediately after (T1), and 6 months after interventions (T2) containing questions relating to change in frequency and severity of PRMDs, ratings of perceived exertion (RPE) during rehearsal, private practice, and performance, as well as nine performance-related factors. Participants were also asked to rate whether these performance-related factors affected their overall playing capacity during different playing situations. A comparative control group of musicians had no intervention and completed a modified questionnaire at the same time points. RESULTS: Exercise participants (n=30) reported a reduction in frequency (p<0.05) and severity (p<0.05) of PRMDs at T1 but not at T2 compared to controls (n=23). The exercise group reported a significant improvement in RPE during private practice at T1 (p<0.01) and T2 (p<0.01), but not during rehearsal and performance. At T1, the intervention was rated to be moderately to highly effective for three performance-related factors: strengthening muscles that support playing, learning techniques that support playing, and posture. Further, participants reported an intervention effect on overall playing capacity during rehearsal at T1 and T2. CONCLUSIONS: A tailored exercise program for musicians was effective at managing PRMDs, especially in reducing the frequency and severity of PRMDs. Physical therapy exercises should be considered in modifying performance-related factors that have been reported to be predictors of PRMDs.

Background Little is known about the effectiveness of exercise programs after decompression surgery for subacromial impingement syndrome. For patients with difficulty returning to usual activities, special efforts may be needed to improve shoulder function. Objective The purpose of this study was to evaluate the effectiveness at 3 and 12 months of a standardized physical therapy exercise intervention compared with usual care in patients with difficulty returning to usual activities after subacromial decompression surgery. Design A multicenter randomized controlled trial was conducted. Setting The study was conducted in 6 public departments of orthopedic surgery, 2 departments of occupational medicine, and 2 physical therapy training centers in Central Denmark Region. Patients One hundred twenty-six patients reporting difficulty returning to usual activities at the postoperative clinical follow-up 8 to 12 weeks after subacromial decompression surgery participated. Intervention A standardized exercise program consisting of physical therapist–supervised individual training sessions and home training was used. Outcome Measures The primary outcome measure was the Oxford Shoulder Score. Secondary outcome measures were the Constant Score and the Fear-Avoidance Beliefs Questionnaire. Results At 3 and 12 months, follow-up data were obtained for 92% and 83% of the patients, respectively. Intention-to-treat analyses suggested a between-group difference on the Oxford Shoulder Score favoring the exercise group at 3 months, with an adjusted mean difference of 2.0 (95% confidence interval=−0.5, 4.6), and at 12 months, with an adjusted mean difference of 5.8 (95% confidence interval=2.8, 8.9). Significantly larger improvements for the exercise group were observed for most secondary and supplementary outcome measures. Limitations The nature of the exercise intervention did not allow blinding of patients and care providers. Conclusion The standardized physical therapy exercise intervention resulted in statistically significant and clinically relevant improvement in shoulder pain and function at 12 months compared with usual care.

The aim of this study was to examine cortical thickness changes associated with a multicomponent exercise intervention combining physical exercise and cognitive training in older adults with cognitive decline. This study involved a secondary analysis of neuroimaging data from a randomized controlled trial with 280 older adults having cognitive decline who were randomly assigned to either a multicomponent exercise group (n = 140) that attended weekly 90-minute exercise and cognitive training sessions or a health education control group (n = 140). The cortical thickness and cognitive performance were assessed at the baseline and at trial completion (10 months). The cortical thickness in the frontal and temporal regions was determined using FreeSurfer software. Cognitive performance was evaluated using the Gerontology-Functional Assessment Tool (NCGG-FAT). The cortical thickness significantly increased in the middle temporal (p < 0.001) and temporal pole (p < 0.001) in the multicomponent exercise group compared with the control group. Cortical thickness changes were significantly associated with change in trail making test (TMT)-A, TMT-B, and story memory after a 10-month multicomponent exercise intervention. This study suggests that multicomponent exercise programs combining physical exercise and cognitive training have important implications for brain health, especially in providing protection from age-related cortical thinning.

We assessed the effects of a 16-week primary-care-based exercise program on body composition in perimenopausal women. The women (n = 150) were randomized into control (n = 75) or exercise (n = 75) groups. Exercise was provided in a 16-week (60 min/session, 3 days/week) concurrent program. Body composition was measured using dual-energy X-ray absorptiometry. These are secondary analyses of the FLAMENCO Project (Clinical Trials Reference NCT02358109). In the intention-to-treat analyses, the control group showed no changes in body mass index (BMI) between post- and pre-test, whereas the exercise group showed a 0.75 kg/m2 decrease in BMI (95% CI: −1.29 to −0.22; p = 0.006). Gynoid and android fat mass in control group decreased by 98.3 g and 46.1 g after the 16 weeks, whereas they decreased by 213 g and 139 g in the exercise group, respectively (95% CI: −209 to −3.86; p = 0.042 and 95% CI: −164 to −26.9; p = 0.007, respectively). The control group decreased their pelvis bone mineral content by 2.85 g in the post-test compared with the pre-test, whereas the exercise group increased it by 1.13 g (95% CI: 0.93 to 7.81; p = 0.013). Per-protocol analyses showed similar results. These analyses suggest that the exercise intervention decreased fat depositions and BMI. Exercise might improve bone mineral content in specific areas such as the pelvis.

Objective The aim of this study was to investigate the effect of 8-week moderate-intensity and high-intensity accumulated exercise on insulin resistance in mice, compared with the moderate intensity continuous exercise with equal workload, which will provide an experimental reference for seeking a more reasonable and effective exercise program to break sedentary behavior and improve metabolic diseases such as IR. Methods Eighty 4-week-old C57BL/6J mice were randomly divided into normal diet group (group C) and high-fat diet group (group H), fed with different diet. At the 10th weekend, insulin resistance model was judged by OGTT curve (AUC) and fasting blood glucose. All mice with insulin resistance were randomly divided into four groups: IR control group (IC), IR moderate-intensity continuous exercise group (IE), IR moderate-intensity accumulated exercise group (IM), IR high-intensity accumulated exercise group (IH), retained normal diet control group (C), with 12 mice for each group. All groups were fed with normal feed. The three exercise-related group performed an 8-week’s treadmill exercise program with equal workload (involve preparation and relaxation activities,0°platform slope, 5 days/week). For IE group, mice run 50min continuously with the velocity of 11m/min. For IM group,mice exercised 12.5 min per session, total 4 sessions per day, with 3-hour’s interval and the velocity of 11m/min. The IH group performed an alike exercise program with IM group, except the running speed (19m/min) and exercise time (7.5min). On the 8th weekend of exercise, FBG, OCTT, FINS, HOME- IR, and ISI were tested for each groups. Results 1. Compared with group C, body weight, FBG and OGTT-AUC were significantly increased in group H (P<0.05 or P<0.01). 76% mice were induced to insulin resistance successfully.  2. Before and after exercise intervention of 8 weeks, there were no significant changes in body weight and OGTT-AUC, while the FBG was significantly increased in IC group (P<0.05). Body weight, FBG, and OGTT-AUC significantly decreased in IE group, IM group and IH group (P<0.05 or P<0.01). 3. After 8 weeks of exercise intervention, the FBG in the IE group, IM group, and IH group were significantly lower than that in C group (P<0.05 or P<0.01). Compared with the IC group, the FBG, FINS, OGTT-AUC, and HOME-IR in IM group, IH group and IE group were lower than those in the IC group (P<0.05 or P<0.01). Compared with the IE group, the body weight and HOME-IR index of IH group were significantly lower than those in IE group (P<0.01). Compared with IH group, the HOME-IR in IH group was lower than that in IM group (P<0.05); There was no significant difference between IM group and IE group. Conclusions 1. Chronic moderate-intensity continuous exercise, moderate-intensity accumulated exercise, and high-intensity accumulated exercise all can effectively improve the glucose metabolism and insulin resistance in IR mice. 2.Compared with moderate-intensity accumulated exercise and moderate-intensity continuous exercise, the high-intensity accumulated exercise with equal workload is more effective in reducing the body weight and improving insulin resistance in IR mice.

AbstractPhysical exercise increase is confirmed as a fundamental treatment for hypercholesterolemia patients, but the effect on the arterial stiffness and oxidative stress is still unclear. 74 hypercholesterolemia patients were divided into 2 groups. The exercise group received dietary recommendations and a 3-month exercise program, prescribed according to their first cardiopulmonary exercise tests(CPET), while the control group only received dietary recommendations. All patients underwent blood tests, CPET and brachial-ankle pulse wave velocity (baPWV) studies at enrollment and at 3 months’ follow-up. At the end of 3 months, there was no change in total cholesterol (TC) level in either group. However, in the exercise group, we found maximal exercise parameters increased and baPWV values declined. Meanwhile, there were significant changes in the level of malondialdehyde, 8-isoprostane-F2α and superoxide dismutase. Moreover, the change of baPWV was positively correlated with the change of 8-isoprostane-F2α (r=0.36, P<0.01). In the control group, no change in baPWV or oxidative biomarker was observed. Our findings suggested that regular aerobic exercise could lessen arterial stiffness in hypercholesterolemia patients, even in the context of no obvious TC decrease. During this process, favorable adjustment in oxidative stress might be an important pathway, which remains to be further explored.

ABSTRACT Introduction: In the last decades, unhealthy habits, such as low levels of physical activity and poor diet, have increased. Consequently, the prevalence of cardiovascular diseases and mortality has increased significantly among adults. However, it is known that regular physical exercises help to improve health outcomes. Thus, the aim of this study was to analyze the effects of eight years of regular participation in an exercise program on blood pressure and mortality in the Brazilian public health system. Methods: The sample consisted of 34 participants with hypertension and/or type II diabetes who were followed up for eight years. They were paired by age, body mass index and chronic disease in two groups: exercise and control. During the follow-up period, medical records were used to assess systolic and diastolic blood pressure, as well as number of medical appointments and the occurrence of deaths. Results: In the follow-up period, five participants died in the control group and none in the exercise group. The Kaplan-Meier analysis identified 29.4% lower mortality among active participants (Fisher's exact test with p = 0.044). The number of medical appointments and the values of diastolic blood pressure were significantly lower for active participants. Conclusion: After a follow-up of eight years, participants in the exercise group attended fewer medical appointments, had better blood pressure control and a lower occurrence of deaths.

Objective: This study evaluated the effect of exercise on heart rate (HR), systolic pressure (SBP), and diastolic pressure (DBP) at different gestational ages during pregnancy. Methods: The exercise intervention and control groups from a previous multi-intervention clinical trial were used. Ninety-two pregnant women were analysed [control group: n = 48; exercise group: n = 44]. The outcome variables were the percentage change in SBP, DBP, and HR during follow-up intervals (16–20 weeks, 20–24 weeks, 24–28 weeks, and 28–32 weeks).Results: resting HR showed a lower increase in the exercise group than in the control group during the interval of gestational weeks 16-20 (p=0.011) [Median Interquartile range: 8.8 (0 to 27.9) control group; 2.2 (-6.9 to 8.1) exercise group]. During this same interval SBP decreased in both control and exercise groups, with more decrease in the control group (P<0.05) [Median Interquartile range: -4.29 (-11.1 to 1.9) control group; -0.89 (-4.76 to 6.36)]. Conclusion: Aerobic exercise in pregnancy significantly attenuated increase of resting HR at the beginning of the second trimester of pregnancy.
